15 marbles into 3 groups

15/3 = 5

3 groups of 5 marbles in each group

What do you want us to do?

To divide 15 marbles into 3 groups, you can follow these steps:

Step 1: Determine the number of marbles you want to place in each group. In this case, you want to put an equal number of marbles in each group.

Step 2: Divide the total number of marbles (15) by the number of groups (3). This will give you the number of marbles in each group.

15 marbles รท 3 groups = 5 marbles per group

Step 3: Place 5 marbles in each group until you have allocated all 15 marbles.

Group 1: Place 5 marbles
Group 2: Place another 5 marbles
Group 3: Place the remaining 5 marbles

By following these steps, you will have evenly divided 15 marbles into 3 groups, with each group containing 5 marbles.
